No experience, but I can offer a clue. The quality of the battery is
often proportional to the amount of lead inside. Look at the net
weight of the battery for a rough idea. The above kit of two 12V 18A
batteries is 12 lbs each. For example, the "plus" version of the same
batteries, from the same vendor:
is 13 lbs per battery.
Same from other vendors:

rest assured that's some no-name chinese battery and quality wasn't a
design concern, at all.
Stick with panasonic or yuasa if you care about quality. Some of those are
from china now, but are less bogus than the rest of the stuff out there.
It's certainly full of prejudice, but that's our stock in trade around
here. If you work in electronics for a couple of decades you build up
useful prejudices without explicitly knowing what they are based on.
It's unscientific, but science is a tolerably expensive way of
building up a body clearly connected facts, while prejudice is cheaper
and less reliable, but a great deal better than nothing, particularly
when science hasn't got around to quantify what you need to know.
As for innuendo
there's nothing indirect about opinion being presented - its a plain
statement of opinion, without any obvious hidden agenda.
